Proposal: Deprecate portable_audio_player.access_method

[Jeff Mitchell]

Wanted to toss this out to people:

With the portable_audio_player.access_method.(protocols, drivers) keys (not up 
on the official site, a build of current documentation from git is at 
http://jefferai.com/stuff/hal-spec.html#device-properties-portable_audio_player ), 
there's no longer really a need to have the plain old 
portable_audio_player.access_method.  Importantly, this key can be outright 
misleading, as some devices can be both (such as Rockbox devices, which can 
use both "storage" and "ipod" protocols), and an application may skip 
checking the portable_audio_player.access_method.protocols key if they see 
that a device has been marked as "storage" in 
portable_audio_player.access_method.  So I propose it be deprecated in favor 
of simply using the .protocols and .drivers keys, which contain the same 
information without this limitation.

That being said, would it then be best to change

portable_audio_player.access_method.(protocols, drivers)

to

portable_audio_player.(protocols, drivers)?

It does still make sense to have it under access_method, I just don't know if 
that's "weird" if there's no top-level access_method key.
